A sub-grid-scale model for polydisperse bubbly flows with heat and mass transfer
Anand Radhakrishnan, Spencer H. Bryngelson
Ensemble-averaged models of polydisperse bubbly flows require statistics of the evolving bubble population. Prior quadrature-based moment formulations close bubble pressure with a…

Shocks without shock capturing: Information geometric regularization of finite volume methods for Navier--Stokes-like problems
Anand Radhakrishnan, Benjamin Wilfong, Spencer H. Bryngelson +1
Shock waves in high-speed fluid dynamics produce near-discontinuities in the fluid momentum, density, and energy. Most contemporary works use artificial viscosity or limiters as nu…
